Bonded polystyrene bead insulation for Downpatrick properties

Downpatrick is among the towns we cover in County Down, alongside Newtownards, Banbridge and Bangor. It is roughly 22 miles south of Bangor.

Downpatrick properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. For semi-detached and terraced homes in Downpatrick, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Exposure matters for every cavity wall. Parts of County Down face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

As for paperwork, in Downpatrick inserting cavity wall insulation needs a building control application to the council before work starts.

What to know before you choose beads

Polystyrene is combustible, so beads are not the right choice for every building; height, use and nearby openings matter, and the system certificate sets the limits. PVC-sheathed cables in the cavity should be sleeved or kept out of contact with the beads where the certificate requires it. We check both at survey.

What is included in Downpatrick

  • Certified bonded bead system
  • Making good to the mortar colour
  • Regulations route and guarantee named on the quote
  • Cable and opening checks at survey
